IMHO, it's a wrong "setup" command during grub installation or you changed some drive after installation (GRUB can't find the menu.lst file). Some tips: - (hd0,0) is equivalent to /dev/sda1 partition - (hd0) is equivalent to /dev/sda disk - you can modify your menu.lst entries at the GRUB prompt by pressing "e". Maybe you got the wrong (hdX,Y). - you can boot with a CD/DVD/USB, then chroot into your / and reinstall GRUB.
